The world mustn't become too peaceful.
The times when humans shine most
beautifully come only through conflict.
I'm trying my best to build a coliseum in
pursuit of the aesthetics of battle, but no
one's interested in helping. It's an outrage.

We can't let the world become too peaceful!
People are at their best when they're at war...
My colosseum will be a monument to war!
If I can ever get the help I need to finish it, that is!

The standard spelling is
"coliseum" except when referring specifically
to the Roman Colosseum, because English does strange
things like that.

Although that's vaguely interesting, the main
reason to come here is to nab the Brave Ring accessory hidden
in one of the pots.

コーリンゲンの村
Village of Kohlingen
KOHLINGEN

Another town, this one with lots of water. To start
with, the party tries talking with various residents. A young girl...

きれいな光がやってきたの！
みんながこわがってたけど…
私はあれ… 好き！

A pretty light came here!
Everyone was scared...
But I... liked it!

That shining creature!
So frightening to us all!
But I found it... beautiful!

...a woman nearby...

本当に怪物だったのかしら？
この子の目の前で、ぴたっと止まって
あの時…
とても、やさしい目をしてた…

Was it really a monster?
When it stopped right
in front of my child...
it had very kind eyes...

Was it really a ghost?
It stopped right in front of me. I could see it had gentle eyes...

...and a man.

このまえ、光の怪物が村に飛びこんで
きたんだ。こわかったー…
南のジドールのほうへ飛んでいったよ。

A monster of light flew into the village
earlier. That sure was scary...
It flew south toward Jidoor.

Everyone was scared when the glowing creature stopped here.
It left to the south, toward Jidoor.

Other people talk about other things.

そこに見える家には、むかし
レイチェルという娘が住んでいた。
今はもうだれもいないがな…

The house you can see there is where
a girl named Rachel used to live.
There's no one's there now, though...

A girl named Rachel used to live in that house.
Now it's deserted.

Having Lock in the party triggers a scene
inside the house here. 2-4 "Forever Rachel" plays
as the scene starts.

{ﾛｯｸ}「俺はあいつを…
守ってやれなかった…

{Lock}: I couldn't...
protect her...

{LOCKE}: ...wasn't able to...
save her when she needed me...

Flashback time... the color changes to a sepia
tint like old photographs. Lock and a woman are shown in a cave.

ﾚｲﾁｪﾙ「{ロック}！
今日のトレジャーハンティングは
何なの？

Rachel: {Lock}!
What treasure are we hunting
for today?

RACHEL: {LOCKE}!
What are we off to find today?

{ﾛｯｸ}「もうすぐおまえの…

{Lock}: You're just about to...

{LOCKE}: Soon, you'll...

He cuts himself off, perhaps having second
thoughts about what he was about to say.

It was a year later...
When I returned here, Rachel was
gone from this world, thanks to an
Imperial attack...
Her memory returned just before death...
They said she called... my... my name...
I never should have left Rachel's side
back then...
I...
I couldn't protect her...

A year passed...
When I returned here, I learned that Rachel had perished in an Imperial attack.
Her memory returned just before she passed away.
The last thing she uttered was... my name...
I should never have left her side.
I...
I failed her...

There's also a house off by itself at the edge
of town, and "??" plays inside. In the basement, there's
an old man, many flowers, and what appears to be a woman
sleeping on a bed.

With that potion I happened to have
on hand then, this girl will stay as she
is, without aging, for all eternity...!
Keh, keh, keh...
Just had to meet {Lock}'s most
earnest of requests...
There wasn't no way I couldn't
use the potion...

I used some herbs to put her into suspended animation.
She won't age a day! Uwaa, ha!
That's what you wanted, right?
Had to use my herbs, I did!

薬 (kusuri)
is a very general term for medicines
(including pills, salves, and liquids), chemicals, and all sorts of
related things, and can also be used figuratively just to make
things more difficult for translators :) . Potion seems a likely
meaning given the context.

Another flashback starts, with the same sepia
tint and "Forever Rachel" music as the other one. This
one takes place in this basement...

Lock stands over the rather familiar-looking woman.
The room looks just as it does in the present.

{ﾛｯｸ}「レイチェル…

{Lock}: Rachel...

{LOCKE}: Rachel...

The old man enters the room.
Lock looks up.

{ﾛｯｸ}「本当にその薬は
きくんだな？

{Lock}: Will that potion
really work?

{LOCKE}: You mean those herbs have actually saved her?

もちろん、もちろん。
あんたの大事な人のなきがらは
このま～んまの姿で、永遠に 永遠に
保存されまっせ。 けっ けっ けっ…

Of course, of course.
Your precious one's remains
will be preserved just like that
for ever and ever. Keh, keh, keh...

Of course!
The love of your life will sleep here like this forever.
Kwa, ha, ha!
